Suggestion: Add 'Faction Headquarters" for each NPC faction

[SiliconMoose]

Give each faction a physical headquarters, either in space or on the planet. Something that is both well defended and provides unique services to allied player factions.

A few example services

• Access to material and component sales at a discount. (Discount could be proportional to how much support a player faction has provided)
• Allow players to buy NPC ships for their own use
• Allow allied player factions to build inside an NPC faction exclusion zone. Something like a 10km diameter zone around the faction headquarters, where any neutral player is given a warning and then attacked after the warning is up, or enemy players are attacked on sight (use MES to spawn attack ships after entering the territory)

I've thought about putting some kind of space port or other building inside the territory safe zone. I've also thought that I could have a ship sales building as an NPC building spawn. I'd love to put an "embassy" at Farpoint that uses a sensor so that you can only get in the embassy if you are neutral or allied to that faction.

If we sell faction NPC ships at those, they'd probably need a little bit extra work for toolbars, extra thrust, and so on.
